Why are you so square? Cerda advocated creating the Eixample as a tight grid plan of equally sized blocks after extensively researching the city and its population. The blocks were also all orientated NW-SE to guarantee that each residence received adequate natural light each day. This was important since Spain at the time did not have an industry capable of producing glass panes.
The Eixample's architecture is eclectic, with styles including Gothic, Baroque, Art Nouveau, and Modernism. It features streets named after artists such as Gaudí and Miró, and houses including museums and hotels designed by some of Europe's most renowned architects (such as Gaudí himself).
In addition to being a center of commerce and culture, the Eixample also serves as a residential area of Barcelona. Many residents work in the city center, but many others work abroad and send money home to their families every month. This creates demand for luxury apartments in the Eixample because few people can afford to live here.
Over the years, many businesses have moved out of the city center and relocated to the Eixample due to its proximity to local universities and schools. Today, students account for 25% of the district's population. The other main population groups are professionals working in finance, law, consulting, and tourism. There are also a large number of elderly people living in the Eixample.
The square form would be a terrible waste of space down there. It is the outcome of how the United States has planned and surveyed territory since the Revolutionary War's end. Because a grid method was used to survey any territory added to the US after 1783, every city created after 1785 will be planned on a grid. Before then, towns were founded anywhere and were usually just collections of houses built around a church or market place. After that, surveyors tried to divide up the land as evenly as possible into small squares with straight roads running through them. When a town grew too large for this system, it was divided into districts and new streets named according to direction: north, south, east, and west.
American cities have no central business district because they were not meant to support industry. The population was expected to be low and stay that way, so most buildings were made out of wood and had thin walls compared to modern cities. Only major cities like Boston began to build stone or brick commercial centers, but they were always located near the waterfront where goods could be shipped in and people could travel by boat. By the 1840s, as industries started moving into America, these center cities grew exponentially and now account for most of the country's wealth and productivity.
As time went on, the idea of putting streets on opposite sides of a block became impractical because of the cost.
The city center was constructed on the old colonial basis. It features a grid system of tiny streets built out at right angles. This rectilinear pattern extends across more than 20 square blocks, a region that established the city's boundaries until the late nineteenth century. The central plaza is surrounded by buildings in this style, including the government palace and the cathedral.
Each block has an average area of about 100 yards squared, but can range up to three times as large or small. The smallest are used for residential homes, while the largest are used for commercial or public purposes.
The majority of city centers around the world are built according to the same basic plan: a grid system of streets lined with office buildings, shops, and restaurants. In fact, many cities were originally founded around a central market place served by a series of roads leading away from it. As they grew larger, these road networks became important routes for trade and transportation, so they were gradually replaced by orthogonal (straight) streets when the new cities were planned out.
In Europe, the early modern period saw the emergence of downtown areas. But it was not until the mid-nineteenth century that they began to take shape in a significant way. Central Paris was rebuilt following the 1852 earthquake, replacing long stretches of urban sprawl with a grid of wide boulevards flanked by symmetrical rows of tall buildings.
Paris's Eiffel Tower is well known all over the world. It is a metallic structure that stands 324 feet (97 m) high and has been used as a radio tower, television antenna, and wind turbine blade manufacturer.
The tower was built by Gustave Eiffel for the World's Fair of 1889. After the fair ended, it was purchased by the French government and has been operated by the French company AFNOR since 1986. There are three levels: the first two are opened to visitors, while the top one is restricted to staff members and their guests.
It is estimated that about five million people visit the tower each year. The number of tourists who visit it every month averages out at more than 250,000.
The tower is especially popular among young adults. About half of those who attend an event on the top floor are between 18 and 34 years old.
There are many other important buildings in Paris.
